Clarksville City is a city in Gregg and Upshur counties in the U.S. state of Texas. The population was 780 at the 2020 census.

The first settlers arrived in the Place before 1845. There was a stagecoach stop at the home of William W. Walters, which was well along owned and operated by Warren P. Victory. Though first known as “Gilead”, the herald office was named “Point Pleasant” in 1852. It closed in 1867. The community withered taking into account the railroad bypassed it in 1873 and Gladewater was established. With the advent of the East Texas Oil Field in 1930, so many homes, businesses, and oil-company camps and offices sprang happening along the highway that it was called the Main Street of Texas, and street numbers were designated from Longview to Gladewater. The area around George W. Clark’s home on the site of the old stagecoach stop became known as “Clarksville”.

After extensive paving projects and new civic improvements in the 1940s and the construction of Lake Gladewater in 1952, the within reach city of Gladewater had a tall tax rate and was extending its boundaries. Industrialists in the area to the east became frightened at the prospect of brute taken into Gladewater and taxed more. A goings-on to incorporate, spearheaded by several oil companies and the L. W. Pelphrey Company, a general contractor specializing in oilfield construction, culminated in a vote to sustain Clarksville City upon September 14, 1956. Pelphrey was elected mayor and served until his death in August 1961. The bypassed ration of Old Highway 80 is named Pelphrey Drive in his honor.

The population dwindled as drilling reached the state tolerable and producing wells became automated. Cities Service Oil Company closed its office and camp in the ahead of time 1960s, and Sun Oil Company soon followed. After a population low of 359 in the 1960s, growth was steady. In 1990 Clarksville City had 720 residents and twenty businesses. In 2000 the population was 806. The town has an elected mayor and council behind a city officer form of government. The city hall was built in 1962 and doubled in size in 1991. A Texas historical marker for the out of date community of Point Pleasant is at the city hall.
